Default Crossmember torque specs...

Hey all... I've searched and Haynes manual isn't helping either.

What's the torque spec for trans cross member to subframe??? Also, the trans mount to crossmember?
TIA...

I know this is an ancient thread but it has caused me a lot of grief. The torque specs for the transmission cross member outer bolts is way off and you will strip the bolts and the threads in the sub frame at 66ft pounds. Think about it, that is only 11ft less than the main transmission mount bolt which is like 4 times bigger!? I ended up going to 37ft and using blue lock tite. Hope this saves someone a lot of grief. Also, wherever you see those bogus torque specs, add a correction or delete the thread...
